High-entropy carbide ceramic and preparation method thereof
The embodiment of the invention provides high-entropy carbide ceramic and a preparation method thereof. The high-entropy carbide ceramic comprises the following components in parts by weight: 50-60 parts of carbide ceramic powder; 10 to 15 parts of nano zinc oxide; 3 to 6 parts of graphene; 5 to 9 parts of 1-ethylimidazole; and 20-25 parts of an organic solvent. According to the embodiment of the invention, the nano zinc oxide, the graphene and the 1-ethylimidazole are added into the carbide ceramic powder; wherein the graphene and the nano-zinc oxide can act together, so that the compressive strength of the ceramic material is improved, the lattice gap is reduced, and the crack propagation and breakage are reduced, thereby improving the fracture toughness of the carbide ceramic; meanwhile, on the basis of the graphene and the nano zinc oxide, the 1-ethylimidazole can optimize the distribution and arrangement of the ceramic powder, so that the mechanical strength and the structural stability of the carbide ceramic can be enhanced.
本申请实施例提出了一种高熵碳化物陶瓷及其制备方法；以重量份数计算，所述高熵碳化物陶瓷包括：碳化物陶瓷粉：50‑60份；纳米氧化锌：10‑15份；石墨烯：3‑6份；1‑乙基咪唑：5‑9份；有机溶剂：20‑25份。本实施例通过在碳化物陶瓷粉中加入纳米氧化锌、石墨烯和1‑乙基咪唑；其中，石墨烯和纳米氧化锌能共同作用，提高了陶瓷材料的抗压强度，并缩小了晶格间隙，降低了裂纹扩展和破碎，从而提高碳化物陶瓷的断裂韧性；同时，在石墨烯和纳米氧化锌的基础上，1‑乙基咪唑能优化陶瓷粉末的分布和排列，有助于增强碳化物陶瓷的机械强度和结构稳定性。
